Beskrivning

The existence of strongly convecting layers in the Sun and stars provides us with a natural laboratory for the study of dynamical processes in intensely turbulent, magnetized, rotating, radiating fluids. Helioseismology h as now given us a tool to measure the detailed properties of solar convection beneath the visible Sun, and thus to test our understanding of the nature of convection and of its influence on stellar structure and the radiative magnetohydrodynamics of solar convection. Presenting and incorporating the newest results from numerical hydrodynamic simulations and helioseismic observations, these contributed papers present the very latest developments in each of these fields.
